This week I am in Costa Rica to celebrate[Earth Day] and promote IBM's [Smarter Planet strategy] to help solve the world's energy and environmental problems. This is thethird in the series. The first two posts were:
Here in Costa Rica, they separate their recyclables, and encourage even the hotel guests from other countries to do the same. See my photo on the left for an example.
This is more than most in the United States will do. We're lucky to get North Americans to just separate all recyclables in one bin separate from all trash in a second bin.
Leaving Arenal, I went to Escazu, a suburb of San Jose, the capital of this country. I met with Patrick, one of the owners of [Exclusive Excursions Travel] that helped me organize the eco-tourism portion of this trip to Costa Rica.
Most people are familiar with the [star rating system] that rank most hotels from one star (budget class/economy) to five stars (deluxe/luxury). The nicest hotel I've been to was the [Burj Al Arab] in Dubai, which claims a seven star rating. For eco-tourism, there is a similar "Green Leaf" rating system. According to Patrick,the Instituto Costarricense de Turismo [ICT] (tourism board of Costa Rica) rates hotels from one leaf (adopting some measures, like separating recyclables shown above) to five leaves (entirely carbon neutral).This Green Leaf system seems more important to European and Canadian tourists, but those from United States may not even be aware of it.
The food at these hotels vary. The typical dish here for breakfast, lunch and dinner is the Casado, consisting of mostly rice and beans. I have found thatCosta Rica has come up with as many creative ways to combine rice and beans in various proportions as Starbucks® serve various combinations of coffee and milk.The locals might be accustomed to a steady diet of rice and beans for every meal of every day, but those of us from North America aren't! Not counting tourist flatulence, Costa Rica has[pledged to be carbon neutral by 2021], the country's 200th birthday.
Sadly, most folks in the United States don't categorize their hotels with a Green Leaf rating system, nor do they even bother to categorize their recyclables. I spent 18 months in the field doing Information Lifecycle Management (ILM) assessments for clients, and most didn't categorize their data either.So, the next time you have some combination of coffee and milk, whether its a Latte, Misto, Espresso, or Macchiato, remember that the coffee came from acountry trying to be more environmentally responsible, grown by a farmerwho eats a simple diet of rice and beans, and has no problem separating different categories of recyclables. Perhaps you will remember to separate your data, and store it on an information infrastructure based on an environmentally-responsible combination of SSD, FC, SATA and tape, to reduce your costs and minimize your carbon footprint.
We've been quite busy here at the Tucson Executive Briefing Center. I am often asked to explain the relationship between IBM's various storage products. While automakers don't have to explain why they sell sports coupes, pickup trucks and minivans, this analogy does not adequately cover IT storage products. So, I have come up with a new analogy that seems to be a better fit: foundations and flavorings.
All over the world, meals are often comprised of a foundation, perhaps rice, potatoes or pasta, covered with some form of flavoring, sauces, pieces of meat or fish, grated cheese and spices. In Puerto Rico, I had dishes where the foundation was mashed bananas called [plantains]. Sandwich shops often let you pick your choice of bread, the foundation, and then your meats and cheeses, the flavorings.At our local steakhouse,[McMahon's], the menulists a set of steaks, the foundation such as Rib Eye, Filet Mignon, Prime Rib or New York Strip, andvarious flavorings, such as sauces and rubs to cover the steak. Last night, I had the Delmonico steak with the Cristiani sauce consisting of Portobello mushrooms, garlic and aged Romano cheese.
This serves as a useful analogy for IBM's storage strategy. Allowing thefoundations and flavorings to be separately orderable greatly simplifies the selection menu and providesa nearly any-to-any approach to meeting a variety of client needs.Let's take a look at both.
IBM's foundation products are the DS family [DS3000, DS4000, DS5000, DS6000 and DS8000 series], [DS9900 series], and [XIV] for disk, and the TS family [TS1000, TS2000, TS3000] series for tape drives and libraries. In much thesame way you might prefer brown rice instead of white rice, or linguine instead of penne pasta, you might find the attributes of one storagefoundation more attractive based on its performance, scalability and availability features for yourparticular application workloads.
Fellow IBM blogger Barry Whyte discusses SVC at great length on his [Storage Virtualization] blog. Flavoring disk foundation storage with SAN Volume Controller can provide you additionalfeatures and functions, and help improve the scalability, performance or availability characteristics.For example, if you have DS4000, DS8000 and XIV, you might use SVC to provide a consistent methodologyfor asynchronous replication, a form of consistent "flavoring" if you will.
N series Gateways
The [N series gateways] offerflavoring to disk foundation, including unified NAS, iSCSI and FCP protocol host attachment, and application aware capabilities. (As for our IBM N series appliances or "filers", these could be foundational storage behind an SVC, but that's perhaps a topic for another post.)
SoFS provides a global namespace with clustered NAS access to files. This is a blended disk-and-tape solution with built-in backup and Information Lifecycle Management [ILM]. Policies can be used to place different files onto different tiers of storage, automate the movement from tier to tier, including migration to tape, and even expiration when the data is no longer needed.
The [IBM System Storage DR550] provides Non-erasable, Non-rewriteable (NENR) flavoring to storage. While the DR550 comes with internal disk storage, it can front end a tape library filled with WORM cartridges. The DR550 hasbeen paired up with small libraries (TS3200 or TS3310) as well as larger libraries like the TS3500.
The IBM Grid Medical Archive Solution [GMAS] provides a variety of capabilities for storing and accessing medical images, using a blended disk-and-tape approach. This allows hospital and clinicnetworks to provide access for doctors and radiologists from multiple locations.
Many of the flavorings are called "gateways". The IBM TS7650G flavors disk that provides a virtualtape library[VTL] with inline data deduplication capability. Recent performance tests pairing the TS7650G flavoring with XIV foundation storage found this combination to be an excellent match.
Let me know what you think. Does this help you understand IBM's storage strategy and acquisitions? Enteryour comments below.
Wrapping up this week's theme on ways to make the planet smarter, and less confusing, I present IBM's third annual [five in five]. These are five IBM innovations to watch over the next five years, all of which have implications on information storage. Here is a quick [3-minute video] that provides the highlights:
Well it's Tuesday, and ["election day"] here in the USA, and again IBM has more announcements.
IBM announced [IBM Tivoli Key Lifecycle Manager v1.0] (TKLM) to manage encryption keys. This provides a graphical interface to manage encryption keys, including retention criteria when sharing keys with other companies.
TKLM is supported on AIX, Solaris, Windows, Red Hat and SUSE Linux. IBM plans to offer TKLM forz/OS in 2009. TKLM can be used with Firefox or Internet Explorer web browser. This will include the Encryption Key Manager (EKM) that IBM offered initially to support encryption keys for the TS1120, TS1130, and LTO-4 drives.
While this is needed today for tape, IBM positions this software to also manage the encryption keys for "Full Drive Encryption" (FDE) disk drive modules (DDM) in IBM disk systems in 2009.
There's some good discussion in the comments section over at Robin Harris' StorageMojo blog for hispost [Building a 1.8 Exabyte Data Center].To summarize, a student is working on a research archive and asked Robin Harris for his opinion. The archive will consist of 20-40 million files averaging 90 GB in size each, for a total of 1800 PB or 1.8 EB. By comparison, anIBM DS8300 with five frames tops out at 512TB, so it would take nearly 3600 of these to hold 1.8 EB. While this might seem like a ridiculous amount of data, I think the discussion is valid as our world is certainly headed in that direction.
IBM works with a lot of research firms, and the solution is to put most of this data on tape, with just enough disk for specific analysis. Robin mentions a configurion with Sun Fire 4540 disk systems (aka Thumper). Despite Sun Microsystems' recent [$1.7 Billion dollar quarterly loss], I think even the experts at Sun would recommend a blended disk-and-tape solution for this situation.
Take for example IBM's Scale Out File Services [SoFS] which today handles 2-3 billion files in a single global file system, so 20-40 million would present no problem. SoFS supports a mix of disk and tape, with built-in movement, so that files that were referenced would automatically be moved to disk when needed, and moved back to tape when no longer required, based on policies set by the administrator. Depending on the analysis, you may only need 1 PB or less of disk to perform the work, which can easily be accomplished with a handful of disk systems, such as IBM DS8300 or IBM XIV, for example.
The rest would be on tape. Let's consider using the IBM TS3500 with [S24 High Density] frames. A singleTS3500 tape library with fifteen of these HD frames could hold 45PB of data, assuming 3:1 compression on 1TB-size 3592 cartridges. You wouldneed 40 (forty) of these libraries to get to the full 1800 PB required, and these could hold even more as higher capacity cartridges are developed. IBM has customers with over 40 tape libraries today (not all with these HD frames, of course), but the dimensions and scale that IBM is capable lies within this scope.
(For LTO fans, fifteen S54 frames would hold 32PB of data, assuming 2:1 compression on 800GB-size LTO-4 cartridges.so you would need 57 libraries instead of 40 in the above example.)
This blended disk-and-tape approach would drastically reduce the floorspace and electricity requirements when compared against all-disk configurations discussed in the post.
People are rediscovering tape in a whole new light. ComputerWorld recently came out with an 11-page Technology Brief titled [The Business Value of Tape Storage],sponsored by Dell. (Note: While Dell is a competitor to IBM for some aspects of their business, they OEM their tape storage systems from IBM, so in that respect, I can refer to them as a technology partner.) Here are some excerpts from the ComputerWorld brief:
For IT managers, the question isnot whether to use tape, but whereand how to best use tape as part of acomprehensive, tiered storage architecture.In the modern storage architecture,tape plays a role not onlyin data backup, but also in long-termarchiving and compliance.
“Long-term archiving is the primaryreason any company shoulduse tape these days,” says MikeKarp, senior analyst at EnterpriseManagement Associates in Boulder,Colo. Companies are increasinglylikely to use disk in conjunctionwith tape for backup, but for long-termarchiving needs, tape remainsunbeatable.
After factoring inacquisition costs of equipment andmedia, as well as electricity and datacenter floor space, Clipper Groupfound that the total cost of archivingsolutions based on SATA disk, theleast expensive disk, was up to 23times more expensive than archivingsolutions involving tape. Calculatingenergy costs for the competing approaches,the costs for disk jumpedto 290 times that of tape.
“Tape isalways the winner anywhere costtrumps anything else,” says Karp.No matter how the cost is figured,tape is less expensive.
Beyond IT familiarity with tape,analysts point to other reasons whyorganizations will likely keep tapein their IT storage infrastructures.Energy savings, for example, is themost recent reason to stick withtape. “The economics of tape arepretty compelling, especially whenyou figure in the cost of power,”Schulz says.
So, whether you are planning for an Exabyte-scale data center, or merely questioning the logic of a disk-for-everything storage approach, you might want to consider tape. It's "green" for the environment, and less expensive on your budget.
Well, it's Tuesday again, and that means more IBM announcements!
Storage Area Network (SAN)
IBM and Cisco announced [three new blades] for the Cisco MDS 9500 seriesdirectors: 24-port 8 Gbps, 48-port 8 Gbps, and 4/44 blended. The 4/44blended has 4 of the faster 8 Gbps ports, and 44 of the 4 Gpbs ports,so that you can auto-negotiate down to 1 Gbps for your older gear, andstill take advantage of the faster 8 Gbps speeds during the transition.
On the Brocade side, IBM announced the newIBM System Storage Data Center Fabric Manager [DCFM] V10 software. This replaces the products formerly known as BrocadeFabric Manager and McData Enterprise Fabric Connection Manager (EFCM).This software can support up to 24 distinct fabrics, up to 9000 ports,including a mix of FCP, FICON, FCIP and iSCSI protocols.
(On a related note, I heard that Microsoft is planning to rename "Windows Vista" to "Windows 7" next year! Like we say here in Tucson,if it ends in "-ista" it is going to fail in the marketplace! Perhaps EMC should rename their storage virtualization product to "In-7"?).
IBM System Storage DR550
IBM announced today that it now supports [RAID 6 onthe DR550] compliance and retention storage system.
There are a few RAID-5 based EMC Centera customers out there who have notyet switched over to the IBM DR550, and now this might be just the littlenudge they need. For long-term retention of regulatory compliance data,RAID-5 doesn't cut it, you need an advanced RAID scheme, such as RAID-6, RAID-DP or RAID-X.
The DR550 provides non-erasable, non-rewriteable (NENR) storage supportto keep retention-managed data on disk and tape media. It supports 1 TBSATA disk drives and 1TB tape cartridges to provide high capacity at lowcost and "green" low energy consumption.
IBM System Storage N series
Several of our disk systems got improved and enhanced. Let's start withthe IBM System Storage N series[hardware and software] enhancements. IBM now offers high-speed 450GB 15K RPM drives. These are Fibre Channel (FC) drives for the EXN4000 expansion drawers, and Serial Attached SCSI (SAS) drives for the entry-levelN3300 and N3600 models.
The "gateway" models now support a variety of functions that were formerlyonly available on the appliance models. This includes Advanced Single Instance Storage (A-SIS), Disk Sanitization, and FlexScale.
A-SIS is IBM's "other" deduplication function, and I talked about this in my post [A-SIS Storage Savings Estimator Tool]. Disk Sanitization will physicallywrite ones and zeros over existing data to eliminate it, what IBM sometimes calls "Data Shredding".
The last feature, FlexScale, might be new for many. It is software toenable to use of the "Performance Accelerator Module" (PAM). The PAM isa PCI-Express card with 16GB on-board RAM that acts as a secondary cachebehind main memory of the N series controller. Depending on the model,you can have one to five of these cards fit into the controller itself,boosting random read performance, metadata access, and write block destage.
IBM System Storage DS5000
IBM's latest entry into the DS family has been hugely successful.In addition to Linux, Windows and AIX, the DS5000 now supports [Novell Netware and Sun Solaris] operating systems.
For infrastructure management, IBM has enhanced the Remote Support Manager [RSM]that supports DS3000 and DS4000 has been extended to support DS5000 as well. This software can monitor up to 50 disk systems, will e-mail alerts to IBM when something goes wrong, and allow IBM to dial in via modem to get more diagnostic information to improve service to the client. Also, the IBM System Storage Productivity Center [SSPC]which now supports the DS8000 and SAN Volume Controller (SVC) has been extended to also support the DS5000.
IBM XIV Storage System
In addition to 1-year and 3-year maintenance agreements, IBM now offers[2-year, 4-year and 5-year] software maintenance agreements.
RFID labels for IBM tape media
IBM 3589 (20-pack of LTO cartridges) and IBM 3599 (20-pack of 3592 cartridges for TS1100 series)now offer [RFID labels]. These labels match the volume serial (VOLSER) with a 216-bit unique identifier and 256 bits of user-defined content. This can help with tape inventory,and to prevent people from walking out of the building with a tape cartridge stuffed in their jacket.
32GB memory stick
While not technically part of the IBM System Storage matrix of offerings, Lenovo announced their new[Essential Memory Key] which holds 32GB of memory and workswith both USB 1.1 and USB 2.0 protocols.
I wish I could say this is it for the IBM announcements for October, given that this is the last Tuesday of the month, but there are three days left, so there might be just a few more!
Wrapping up my week on successful uses of information, I thought I would discuss the visualization of data.Not just bar charts and pie charts, but how effective visual information can be on multi-variable plots.
IBM's [Many Eyes] recognizes that 70 percentof our sensory input neurons in our brain our focused on visual inputs, and so we might recognize patternsif only data was presented in more interesting and visual representations.
In addition to X/Y axis, variables can be presented by size of circle and color. Here's an example plot of the past US bailouts, with variables representing amount, year, company andindustry. This plot does not include the current 700 Billion US Dollar bailout currently under discussion.
This is part of IBM's Collaborative User Experience (CUE) research lab. The software is available Web2.0style at no charge, just upload your data set, and choose one of 16 different presentation styles.
These plots get even more interesting when you animate them over time. In 2006, Hans Rosling presenteddata he gathered from the United Nations and other publicly funded sources and presented his findings atthe TED conference. Here is the 20-minute video of that presentation (click on play at right), titled ["Debunking third-world myths with the best stats you've ever seen"], in which he debunks the myth that all countries fall into two distinct categories: Industrialized and Developing.
Amazingly, the data--as well as the software to analyze it--is available at[GapMinder.org] Web site.
For more information on how you can deploy an information infrastructure that allows you to search, visualize and leverage the most value from your information, contact your local IBM representative or IBM Business Partner.
"IBM announced that Northwest Radiology Network has gone live with a new virtualized enterprise of IBM servers and storage to support its growing medical imaging needs, giving its four locations an enterprise-class infrastructure which enables its doctors to recover medical image reports faster for analysis and enables remote 24x7 access to its medical image report system.
Founded in 1967, Northwest Radiology (NWR) is ranked as one of the largest physician groups in the Indianapolis, Indiana area. With 180 employees who offer the Central Indiana community comprehensive inpatient and outpatient imaging services such as mammography, ultrasonography, CT scans, PET-CT scans, bone density scans and MRIs – the Network had a dramatic need to develop a centralized infrastructure where large amounts of data could be stored and shared. A new data center would benefit the company’s clientele; which includes area hospitals and doctor’s offices serving thousands of patients each year.
Storing more than ten thousand medical imaging reports and radiographic images each month for doctors to analyze, the Network realized it had single points of failure and at one point a critical report server failed. Northwest Radiology turned to IBM and IBM Business Partner Software Information Systems (SIS) for a more efficient solution to prevent any possible downtime in the future.
SIS recommended and installed a virtualized infrastructure with IBM servers and storage as the heart of Northwest Radiology’s Indianapolis data center. By April 2007, Northwest Radiology replaced eight servers and direct attached storage with just two IBM System x3650 servers connected to an IBM System Storage DS3400. Today, the new servers run 15 virtual servers to ensure the availability of their services 24x7. When the business needs it, a new server can be provisioned in just minutes. With a Fibre Channel on the SAN Disk, the DS3400 not only increased performance but also met NWR’s requirement to not have one single point of failure. With three TB of storage capacity, they can meet the demands of increased business well into the future. The systems are also now easily managed from a remote site."
“Uptime is paramount in our business. We selected IBM based on the reliability and flexibility of IBM System x servers and the IBM System Storage DS3400,” said Marty Buening, IT Director, Northwest Radiology Network. “The virtualized infrastructure and the SAN storage array that SIS and IBM brought to the table is improving our service and giving our doctors and staff piece of mind knowing each patient’s medical imaging reports are always available.”
Second, we have [Iowa Health System], a large enterprise with over 19,000 employees, managing four million patients and hundreds of TBs of data.
Here is a 4-minute video on IBM TV from the good folks at Iowa Health System discussing theIBM Grid Medical Archive Solution (GMAS) as part of their information infrastructure for theirPicture Archiving and Communication Systems (PACS) application.
In both cases, IBM technology was able to provide remote access to medical information, making images and patient records available to more doctors, specialists and radiologists. Last January, in my post[Five in Five], IBM had predicted that remote access to healthcare would have an impact over the next five years.
Whether you are a small company or a large one, IBM probably has the right solution for you.
Continuing this week's theme on customer references of IBM's solutions, today I will discussthe success at Kantana Animation Studios.
Here is a 3-minute video from the good folks at Kantana Animation Studios,part of the [Kantana Group].They produced the animated movie [Khan Kluay]using IBM Scale-out File Services (SoFS), a product IBM announced last November 2007.
As a film-maker myself (see this sample [Highlights clip])and active member of the Tucson Film Society,I am pleased to see IBM so greatly involved in the film industry. I've had the pleasure to visit some of theseanimation studios myself and meet with other film-makers at various conferences.
For more details on Kantana's implementation, see the [Case Study]
Continuing this week's theme about new products that were mentioned in last week's launch, today I willcover the new [S24 and S54 frames].
Before these new frames, customers had two choices for their tape cartridges: keep them in an automatedtape library, or on an external shelf. Most of the critics of tape focus almost entirely on the problemsrelated to the latter. When tapes are placed outside of automation, you need human intervention to findand fetch the tapes, tapes can be misplaced or misfiled, tapes can be dropped, tapes can get liquids spilledon them, and so on. These problems just don't happen when stored in automated tape libraries.
Until now, the number of cartridges were limited to the surface area of the wall accessible by the roboticpicker. Whether the robot rotates in a circle picking from dodecagon walls, or back and forth from longrectangular walls, the problem was the same.
But what about tapes that may not need to be readily accessible, but still automated? With the newhigh density frames, you can now stack tapes several cartridges deep, spring loaded deep shelves thatpush the tape cartridges up to the front one at a time. The high-density frame design might have been inspired by thefamous [Pez] candy dispenser, but at 70.9 inches, does not beat the[World's Tallest Pez Dispenser].
(Note: PEZ® is a registered trademark of Pez Candy, Inc.)
In a regular cartridge-only frame, like the D23, you have slots for 200 cartridges on the left, and 200 cartridges on the right, and the robotic picker can pull out and push back cartridges into any of theseslot positions. In the new S24, there are still 200 slots on the left, now referred to as "tier 0",but up to 800 cartridges on the right. In each slot there are up to four 3592 cartridges, the positionimmediately reachable to the picker is referred to as "tier 1", and the ones tucked behindare "tier 2", "tier 3" and "tier 4".
<- - - S24 frame - - - >
We have fun slow-motion videos we show customers on how these work. For example, in the diagram above, let'ssuppose you want to fetch Tape E in the "tier 4" position. The following sequence happens:
Robotic picker pulls "tier 1" tape cartridge B, and pushes it into another shelf slot. Tapes C, D and E get pushed up to be Tiers 1, 2 and 3 now.
Robotic picker pulls "tier 1" tape cartridge C, and puts it in another shelf slot. Tapes D and E get pushed up to be Tiers 1 and 2 now.
Robotic picker pulls "tier 1" tape cartridge D, and puts it in another shelf slot. Tape E gets pushed up to be Tier 1 now.
Robotic picker pulls "tier 1" tape cartridge E, this is the tape we wanted, and can move it to the drive.
The other three cartridges (B, C and D) are then pulled out of the temporary slot, and pushed back into their original order.
In this manner, the most recently referenced tape cartridges will be immediately accessible, and the ones leastreferenced will eventually migrate to the deeper tiers. The 3592 cartridges can be used with either TS1120 orTS1130 drives. Each cartridge can hold up to 3TB of data (1TB raw, at 3:1 compression), so the entire framecould hold 3PB in just 10 square feet of floor space. Five D23 frames could be consolidated down to two S24 frames.The S24 frame comes in "Capacity on Demand" pricing options. The base model of the S24 has just tiers 0, 1 and 2, for a total capacity of 600 cartridges. You can then later license tiers 3 and 4 when needed.
The S54 is basically similar in operation, but for LTO cartridges. It works with any mix of LTO-1, LTO-2, LTO-3 andLTO-4 cartridges.The left side holds tier 0 as before, but the right side has up to five LTO cartridges deep. For Capacity on Demand pricing,the base model supports 660 cartridges (tiers 0,1,2), with options to upgrade for the additional 660 cartridges.The total 1320 cartridges could hold up to 2.1 PB of data (at 2:1 compression). One S54 frame could replacethree traditional S53 frames that held only 440 LTO cartridges each.
If you have both TS1100 series and LTO drives in your TS3500 tape library, then you can haveboth S24 and S54 frames side by side.
